Grimmspeed Electronic Boost Control Solenoid For The 2008-2012 Wrx on 2040-parts.com

The GrimmSpeed™ Boost Control Solenoid(BCS) plugs in and requires no splicing or soldering of resistors. With the included bracket you can bolt it in, plug in the connector, and start tuning for fast boost response, increased boost pressure and free up lots of power. Planning on returning the car to stock? Just reverse installation.

Why run an Electronic Boost Control Solenoid over a Manual Boost Controller?

A MBC allows you to run higher than stock boost levels by preventing the wastegate from opening at its rated pressure. It does a great job at this but if boost is available under the MBC setting it will give you that full boost. So for instance, you set your MBC to 18psi because from 3000-6000rpm thats what you want. But then say you get detonation with 18psi when you are at 7000rpm unless you are below 16psi. With a MBC, you do not have this control so you are forced to run 16psi through the entire rev range. With an electronic boost controller you could run 18psi from 3000-6000 and 16psi at 7000rpm because you can tune the boost map in the ECU, which will allow you to run the maximum amount of boost at every given rpm. This gives you more power throughout the range and better control. Revolutionizing the boost solenoid market, Grimmspeed has created model specific install brackets that allow you to directly fit their Boost Solenoid into your vehicle for a factory fit. No more Zip-tying! They give you the factory fitment you have been waiting for.

Staying with the OEM fitment theme, Grimmspeed's Boost Solenoid uses an OEM style wiring harness so you can simply unplug your OEM solenoid and plug theirs in. No more cutting the OEM wiring and crimping wires together!

Also new to the boost solenoid market, they have used ultra low-profile hose fittings to keep the unit as small and clean as possible. The hose fittings are nickel plated brass so you don't have to worry about them snapping off like the plastic hose fittings!
